The price of the camera is after the 40% increase, would be $378.
Since the camera's original price was $450, and there was a 40 percent discount, you first find the discount of the original cost. Multiply $450 by 40% (0.4) to get $180. You then subtract $180 from $450 to get $270.
Now they added a 40% increase in price, but this increase is for the current cost $270. So, you multiply $270 by 40% (0.4) to get $108. Finally add $108 to $270. Thus getting $378 as a final answer.
I hope this helps!
